They are almost always fake V1 schematics renamed to OLED.
When docked, the MIPI DSI signal is ignored, and the SoC outputs a DisplayPort signal. This signal routes to a dedicated transmitter chip ( PI3USB30532 or similar multiplexer matrix), which splits the signal into HDMI differential pairs forwarded to the Type-C port.
64GB eMMC 5.1 storage module. Unlike previous models with 32GB, the OLED version doubles internal storage. The schematic maps this onto a detachable modular daughterboard, communicating via an 8-bit parallel MMC interface to the SoC. 2. Power Management Integrated Circuits (PMIC)
The primary Power Management IC (PMIC) responsible for USB-C negotiation and power routing. If your Switch won't charge or dock, this is usually the culprit on the schematic. BQ24193: The battery charging management chip.
